Etymology: Pseudocrenilabrus: Greek, pseudes = false + Latin, crenulatus = cut + Latin, labrum = lip (Ref. 45335); pyrrhocaudalis: Named Pseudocrenilabrus pyrrhocaudalis because this species has a bright orange tail which resembles a flame of fire (Ref. 114630).

Short description Morphology | Morphometrics

Dorsal spines (total): 13 - 15; Dorsal soft rays (total): 8-12; Anal spines: 3; Anal soft rays: 6 - 10. Diagnosis: Pseudocrenilabrus pyrrhocaudalis can be differentiated from the other species of the genus Pseudocrenilabrus on the basis of its colour pattern and its subtruncate caudal fin; male P. pyrrhocaudalis have a unique colour pattern characterized by some orange colour on their anal and caudal fins that can become bright orange-red in breeding males, extending over proximal parts of anal and caudal fins and distal part of caudal and upper and lower parts of caudal peduncle; in addition, P. pyrrhocaudalis can be distinguished from its sympatric congener P. philander by a combination of the following characters: pelvic fin white (vs. black), posterior part of dorsal fin orange (vs. olive green in other species), comparatively thinner lips (vs. comparatively thicker lips), larger eye diameter 27.0–39.3% HL (vs 22.9–33.1% HL), narrower head width 37.0–47.3% HL (vs. 38.5–53.7% HL), narrower interorbital distance 14.6–22.3% HL (vs. 20.5 29.4% HL) and a more slender caudal peduncle 8.8-11.8% SL (vs. 11.3–13.9% SL), and 50.0–64.7% CPL (vs 64.3–93.5% CPL)(Ref. 114630).

Found in demersal seine catches at open beaches (Ref. 114630).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.5 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (11 of 100) .
